A fish leaps vertically upward from the surface of a lake at an initial speed of 9 meters per second. The height h, in meters, of the fish
above the surface of the h = 95 - 4.952. Approximately how many seconds after the fish leaps will it hit the surface of the lake?

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
